i have recompiled and everything have worked very good :) now i am
able to use my notebook without having to stay just at my desk :)
btw where i cad read a little more about those dependencies like SMP
enabled -> have to use usb2.
i have searched on google about how to enable usb2 on the kernel but i
found just exemples of kernel config's and not why it shoul dbe used.
